InfoWorld has an interesting piece on the communications feeding into and out of yesterday’s tragedy at Virginia Tech. I’m not quite so optimistic about the good stuff always rising to the top, but the article makes several points worth considering–including the fact that everyone knows SMS is the best channel for mass communication to students in a time of emergency, though schools are regrettably slow to act on that knowledge. It wouldn’t be hard to set up an emergency cell phone registry. And it would be well worthwhile, in my view.
